`DISK DRILL.

Specification of Letters Patent.

Application mea 'July s, 191e. seran No. 777,204.

To all t0/wm, t may concern:

Be it known that I, HENRY E. LOHMAN, a citizen of the United States, residing at Russell, in the county of Russell and State of Kansas, have invented certain new and useful Improvements in Disk Drills, of which the following is a specification.

The present invention relates to a disk drill, and has for its object to provide a device of this character which is comparatively simple and inexpensive in its construction, and which embodies novel features of design whereby the ground is effectively opened up and the grain properly spread therein.

Vith this and other objects in view,"the" invention consists incertain novel combinations and arrangements of parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, referencel is to be had to the following description and accompanying drawing, in \whioh:-

Figure 1 is a side elevation of a grain drill constructed in accordance with the invention, portions being broken away and shown in section. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical transverse sectional view on the line 3-3 of Fig. 1, and Fig. 4 is a similar view on the line 4 4 of Fig. 1, with the boot in an upright position.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Specifically describing the present embodiment of the invention, the numeral 1 designates the beam which has thel rear end thereof deflected upwardly as indicated at la, while the forward extremity thereof is provided with a clevis 2 or other suitable means for applying draft to the beam. At an intermediate point in the length thereof the beam 1 is provided with a transverse opening within which a tubular bushing 3 is rigidly fitted, the ends of the bushing projecting laterally beyond opposite sides of the beam. A bearing sleeve 4 is journaled within the tubular bushing 3, the said bearing sleeve being provided at one end thereof with a flat disk 5. As shown in the drawing the sleeve 4 is provided at one of its eX tremities with an outstanding flange 4a to which the disk 5 is riveted or otherwise rig- Y idly connected. This bearing sleeve 4 may posed between the nut and the ends of the bushing 3 and bearing sleeve 4. The end of the bolt 6 adjacent the head 6a preferably has an angular or polygonal formation as indicated at 6b for engagement with a corresponding socket in the bearing Vsleeve 4 so as to prevent rotation of the bolt 6 `when placing the nut 7 in position or removing it therefrom.

In order to bring the shovel 10 approximately in alinement with the disk 5, the rear end of the beam 1 is offset laterally as indicated at l". The boot 9 is applied to this laterally offset end of the beam 1 and has an extension 9a at the lower end thereof to which the shovel l() is removably applied in some suitable manner, as by means of the bolt 11. A suitable hopper 12 may be applied to the upper end of the boot 9 if desired. The lower end of the boot 9 and shovel 1() must be disposed immediately in rear of the disk 5 so that the shovel 10 twill open up the slit formed in the ground by the disk 5, the seed being dropped through the boot 9 into the furrow or opening formed in the ground by the combined action of the disk and shovel.

The boot 9 may be mounted upon the end of the stock in any suitable manner, although in the present instance it is shown as pivotally connected to the rear end of the stock by means of a pivot bolt 13. The boot 9 can be swung laterally about the pivot bolt 13 so as to bring the point of the shovel 10 into exact alinement with the disk 5 and proper adjustment thereby made.

Suitable means may be provided for locking the boot 9 against pivotal movement upon the bolt 13, and for this purpose an angle-bracket 14 is shown as applied to the rear end of the beam 1 at the top thereof. One flange of the angle bracket is bolted to the beam as shown at 15, while the opposite ange thereof is provided with a segmental lslot 16 receiving a clamping bolt 17. YThis bolt moves freely within the slot 16 when. loosened, although after the boot has been properly adjusted the said clamping screw 17 is tightened to look the bootv against movement.

Having thus deseribed the invention, what I claim as new and desire to secure by Letters Patent, is:- Y

1. A disk drill `including a beam having a transverse opening therein, a tubular bushing fitted within the opening, a sleeve adapted to be journaled within the bushing, a disk at one end of the sleeve, the said disk `being adapted to be positioned upon either side of the beam, a boot adjustably mounted upon the rear end of the beam, a shovel carried by the boot, the said boot being adapted to be swung laterally to position the pointof the shovel in alinement with the disk, and means for looking the boot in Van adjusted position.

2. A disk drill including a beam having a transverse `vopening therein, a tubular bushing mounted within the opening, a

sleeve journaled within the bushing and adapted to be inserted into the bushing from either end thereof, a disk at one end of the sleeve, said disk being adapted to be positioned upon either side of the beam, means for retaining the sleeve within the bushing, a boot adjustably mounted upon the rear end of the beam so as to have a lateral swinging movement, a shovel carried by the boot and adapted to have the point thereof swung into alinement with the disk, and means for locking the boot in an adjusted posit-ion.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY E. LOHMAN.
